Natural fancy colored diamonds are a rare find and this makes them very expensive. These rarities are usually owned by museums or very rich individuals. So the color enhancement methods create wonderful pieces that look like the rare stone at a very affordable price. You do need to be careful because at the same time a dishonest jeweler or lab may snooker you in to believing a stone is 100% natural in order to hike up the cost. So know that the natural un-enhanced diamond comes with a certificate of authentication and if you are still concerned have another jeweler give you a second opinion on the quality.

The color enhancement of a diamond is achieved in one of three ways, by using the High Pressure – High Temperature method, the Coating method or the Irradiation method. The High Pressure-High Temperature is similar to nature’s process. It causes the imperfections in the diamond to correct themselves changing the color depending on the color of the natural stone. The stone can become colorless, blue, yellow orange, yellow green, pink or brown. The Coating method they apply a super thin layer of a durable coating solution to mask the yellow tints in the stone in order to raise the cost. This method can be undetectable for years if not graded by a reputable lab. The irradiation method infuses the natural stone with high electron particles that creates narrow space and when heated the nitrogen traps the narrow spaces to create a more complex color. The colored centers absorb certain colors reflecting back to us the unabsorbed colors that we see. These colors include green, canary yellow, blue, purple and red which is the rarest and most difficult to achieve color. Then these stones are treated and a hundred percent safe to wear.
